Overview
MCM flexible stone installs like a thin tile but behaves like a sheet: it is bonded to a prepared substrate with a suitable thin-set or polymer-modified adhesive, reinforced with alkali-resistant mesh at joints and transitions, and finished with a flexible grout or trim. Because the material is only 2–9 mm thick, the system adds minimal build-up to walls and columns.
This hub groups the installation guide, substrate preparation notes, the tools checklist and the curved-surface method most requested by contractors. Pair it with the specifications and maintenance hubs.
Substrates MCM Can Go On
MCM bonds to most sound, clean, flat vertical substrates, including:
- Cement render / plasterboard / gypsum board (interior)
- Concrete and masonry
- Existing tile and painted walls (after proper preparation)
- Curved and radiused formwork, columns and arches
- Exterior façade substrates approved for the cladding system
Typical Installation Steps
- Prepare. Ensure the substrate is clean, dry, flat and load-bearing. Repair defects and apply primer where recommended.
- Layout. Dry-fit sheets, plan joints and match texture direction across panels.
- Bond. Trowel a compatible thin-set or polymer-modified adhesive evenly and press the sheet into place, working from the centre outward to release air.
- Reinforce. Embed alkali-resistant mesh at all joints, corners and transitions to control movement.
- Finish. Tool joints, trim edges, and apply the specified sealer or grout where the system requires it.
Do & Don’t
| Do | Don’t |
|---|---|
| Use a notched trowel and full-coverage adhesive | Spot-bond or bridge gaps |
| Reinforce joints with mesh | Leave unprotected edges on wet areas |
| Follow the documented system for the substrate | Mix adhesive brands without compatibility checks |
Frequently Asked Questions
Can MCM be installed on curved walls?
Yes. The 2–9 mm sheet is flexible enough to follow radiused columns, arches and bullnosed edges without cracking — one of the main advantages over rigid stone.
Do I need special adhesive?
Use a compatible thin-set or polymer-modified adhesive recommended for flexible thin veneers and matched to the substrate and (for exteriors) the weather exposure. Avoid generic mastics.
Is it a DIY product?
Small interior feature walls can be handled by experienced installers; exterior façades and wet areas should be carried out by contractors following the documented system to protect the warranty.
